FLY=SCREEN.

SPECIFICATION forming part of Letters Patent No. 356,349, dated January 18, 1887.

Application filed June 28, 1886. Serial No. 206,420. (No model.)

To all whom it may concern.-

Be it known that I, .OHARLEs W. CHATTER- TON, a citizen of the United States, and a resident of Oenterville, in the county of Appanoose and State of Iowa, have invented certain new and useful Improvements in Fly-Screens; and I do hereby declare that the following is a full, clear, and exact description of the in vention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which Figure lis a perspective view from the outside of a screen provided with my improved fly-escape. Fig. 2 is a similar view of the same seen from the inside. Fig. 3 is a vertical sectional View of the same, and Fig. 4 is a perspective detail view of aslight modification of the device.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to that class of fly-screens which are provided with escapes for the flies, which willenable the flies to escape, but which will prevent the flies from again entering; and. it consists in the improved construction and combination of parts of such a screen, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the frame of the screen, which may be fitted into a door, window, or any other suitable aperture in any suitable manner, and B is the screen. A rectangularly and longitudinally bent plate, 0, of sheet metal is secured with its upper flange to the under side of the top piece, D, of the screen bynails, E, or other suitable fastening means, and the down wardlyprojecting flange is provided with a number of perforations, F, being placed at distances from each other and in numbers corresponding to the size of the screen and to the number of escapes employed with the screens of the room or house. Outwardlytapering tubes G are secured upon the outer side of the flangeat theperforations, and these tubes are forced through the screen, preferably, by simply drawing the meshes of the screens at those points so as to form larger apertures.

It will be seen that the tapering tubes projecting outward through the screening and slightly upward will allow the flies to crawl out through them, the flies being attracted by the light on the outside; but when the flies have reached the outer ends of the tubes and should again attempt to enter them the narrow mouths of the tubes will not afford sufficient space for them to alight and pass in, so that with this attachment in a screen the flies Within the room will be attracted to pass out, and cannot enter again after they have once passed out.

Each tube may be attached to a plate of its own and located at any desired part of the screen. However, as fly-escapes consisting of conical tubes secured in window-screens have heretofore been employed, I do not lay claim, broadly, to such escapes; but,

Having thus fully described my invention, I claim 1. A fly-escape consisting of a plate bent longitudinally at a right angle, and having a number of perforations provided with outwardly-projecting and upwardly-inclined tapering tubes at the perforations, as and for the purpose shown and set forth.

2. In combination with a fly-screen, a plate bent longitudinally at a right angle and having a series of perforations, and secured with its upper flange to the toppieceof the screen, I

and having a number of tapering and upwardly and outwardly projecting tubes at the perforations projecting through the screen,

as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two Witnesses.
